* ActorSharedBackground: Jiraiya is Japanese American, like his actor Kane Kosugi.
* BonusEpisode: ''[[Recap/NinjaSentaiKakurangerSuperVideoTheHiddenScroll Ninja Sentai Kakuranger Super Video: The Hidden Scroll]]'' was released with an issue of TV Magazine.
* DawsonCasting: Slightly inverted. Satomi Hirose, playing Tsuruhime, was not yet 14 when filming began. When Tsuruhime is shown celebrating her birthday onscreen mid-series, her birthday cake can be seen holding 16 candles.
* PropRecycling:
** The costume worn by Youkai Mujina's Amazoness assassin in #46 is a reuse of that worn by Tiger Ranger, Boi, from ''[[Series/KyoryuSentaiZyuranger Zyuranger]]''.
** One of the various background Yōkai in a few episodes is in fact the [[FusionDance Combined Four Deva Kings]] from ''Series/GoseiSentaiDairanger'' in a different outfit and given a red wash.
* RealLifeRelative: Jiraiya, played by Kane Kosugi, was the pupil of [[spoiler: his father's killer]], Gali. In real life, Gali was played by Kosugi's ''father,'' Shou.
* WhatCouldHaveBeen: Kane Kosugi was initially cast as Red but his poor Japanese led to his role being changed to Black.
* YouLookFamiliar: The yokai Amikiri's human guise and voice were provided by Ami Kawaii, aka Lamy in ''Series/KyoryuSentaiZyuranger''. Coincidentally her American counterpart, Witchblade (no, not [[ComicBook/{{Witchblade}} that one]]) is ''also'' voiced by Creator/WendeeLee.
